DP590 steel microscopic inclusion oxygen and nitrogen content particle size
- 摘要:
- The type,source,quantity and composition of T[O],T[N]and microinclusions in the billet of DP590 steel(blast furnace ironmaking,BOF,LF refining,continuous casting)were analyzed.The results show that the steady state slab of T[O]=25×10-6,T[N]=27×10-6,the number of micro-inclusions is 8 p/mm-2,the types of microscopic inclusions are as follows:CaS-Al2O3,CaO-Al2O3,Al2O3 and CaS.Particle sizes range from 1~10μm,4~20μm,1~4μm,1~10μm,and the content are 50%,20%,20%,10%,respectively.
